Unity Tool Tips View Error
Hello, I'm running into an error where I can no longer change the name of my game objects in the inspector/Heirarchy. Unity operates normally when first started, but when I attempt to change a name, I can type the name and the text box works normally, but escaping the text box in any form fires an error in Text Tool.Close() as well as a few others.
Here is an image of the error:

Double Clicking on this Error takes us to this screen and often crashes the hierarchy window soon after

There is another error being called at SetAlpha also in TooltipView, shown here.

Double Clicking on this shows nothing.
I am unsure whether this was an error in my use or in Unity, but I am unable to fix the issue.
Things I've tried: - Uninstalling and reinstalling Unity - Deleting and rebuilding the Library
